Abstract
The utility model discloses a kind of fire-proof doors and windows built-in hinges, mounting plate ontology including font, the both ends of the mounting plate ontology, which are bent, is provided with dog-ear portion, and the distance between the medial surface in two dog-ear portions is equal with the width of hinge mounting portion, it is offered on the mounting plate ontology and the same number of second mounting hole of the first mounting hole on hinge mounting portion, and when the hinge mounting portion is installed between two dog-ear portions, each second mounting hole and each first mounting hole coincide one by one.The utility model is by being arranged dog-ear portion at the both ends of the mounting plate main body of 1 font respectively, when assembling hinge on a mounting board, mounting plate vertical folding angular position need to be only blocked with hand, just block the both ends of main hinge mounting portion in its dog-ear portion, the second mounting hole in mounting plate main body is set to match with the hole location of the first mounting hole on hinge, to relaxedly and rapidly complete assembly.
Description
Technical field
The utility model relates to fire-proof doors and windows technical field more particularly to a kind of fire-proof doors and windows built-in hinges.
Background technique
Open and close type after existing built-in hinge is mostly friction-type or keeps window mobile in market, also whether there is or not frictions not to move
Built-in hinge, the first friction-type hinge, friction and the movement for keeping fan mobile are to making it not be able to cooperate fireproof window
It closes after window device realizes chance fire and closes window function.It does not move without friction but has multiple positions that must close using zinc in its structure for second
Gold or aluminum alloy material could complete, kirsite, aluminium alloy fusing point be not able to satisfy the temperature of fire prevention, fireproof window national standard, it is on fire
When temperature is more than 650 ° afterwards, kirsite, aluminium alloy, which can melt, causes window sash dropping to be unable to complete fire prevention.
Utility model content
The purpose of the utility model is to provide a kind of fire-proof doors and windows built-in hinges, solve built-in hinge in the prior art
It is not able to cooperate the technical issues of fire-proof doors and windows complete fire-proof function.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of fire-proof doors and windows built-in hinge of the utility model, including the hinge installation being fixedly connected for the frame with door and window
Plate, the hinge mounting plate are provided with first axle plate and second hinge plate, one end of the first axle plate and described second
One end of flap is articulated and connected with the hinge mounting plate, the other end of the first axle plate and second hinge plate it is another
One end articulated connection；It is provided with shaft above the first axle plate, connecting plate, the connecting plate are arranged in the shaft
It is fixedly connected with the fan of door and window, and maintains certain gap between the connecting plate and the first axle plate.
Further, one end of the shaft extends to the outside of the connecting plate, and with described first after overstriking processing
Flap is fixedly connected, and makes between the connecting plate and the first axle plate that there are certain gaps.
Further, the end of the shaft is provided with gasket, and the gasket is fixedly connected with the first axle plate, makes
There are certain gaps between the connecting plate and the first axle plate.
Further, the hinge mounting plate is fixedly connected by multiple screws with the frame of door and window.
Further, the first axle plate and second hinge plate with the contact position of the screw on the hinge mounting plate
The place of setting offers escape groove.
Compared with prior art, the advantageous effects of the utility model:
The utility model first axle plate and second hinge plate are and hinge mounting plate and first axle plate and the second hinge
It is articulated and connected between carrier bar, reduces the frictional force in each component course of work of hinge, moreover, by the overstriking of shaft bottom
Processing makes to make to connect there are certain gap between connecting plate and first axle plate in the mode of the bottom of shaft setting gasket
Plate will not contact during the motion with first axle plate and second hinge plate, will not generate friction and scratch, reduce movement
Resistance, enable built-in hinge cooperate on fire-proof doors and windows close window device complete fire-proof doors and windows meet fire after close window function, thus
Realize the realization of the effect that uses and prevent fires of fire-fighting fire-proof fire resisting hinges of door and window.

Specific embodiment
Embodiment one:
As Figure 1-Figure 2, a kind of fire-proof doors and windows built-in hinge, including the hinge being fixedly connected for the frame with door and window
Mounting plate 1, the hinge mounting plate 1 are fixedly installed on the frame of fire-proof doors and windows by multiple screws.
First axle plate 2 and second hinge plate 3 be installed on the hinge mounting plate 1, the one of the first axle plate 2
End and one end of the second hinge plate 3 are articulated and connected with the hinge mounting plate 1, the other end of the first axle plate 2
It is articulated and connected with the other end of second hinge plate 3, and the first axle plate 2 and second hinge plate 3 are pacified with the hinge
Escape groove 7 is offered at the contact position of screw in loading board 1.
The top of the first axle plate 2 is fixedly welded with shaft 5, and connecting plate 4, the company are arranged in the shaft 5
Fishplate bar 4 is fixedly connected with the fan of door and window, and one end of the connecting plate 4 is fixedly connected by multiple screws with the fan of door and window, back
Side is equipped with supporting plate 8, and lives by 8 support of supporting plate the edge of the fan of door and window.
In the present embodiment, one end of the shaft 5 extends to the outside of the connecting plate 4, and after overstriking processing with institute
It states first axle plate 2 to be fixedly connected, makes between the connecting plate 4 and the first axle plate 2 that there are certain gaps.
Embodiment two:
The present embodiment only changes the structure of the shaft 5, institute under the premise of not changing the other structures of embodiment one kind
